[merged mm-stable] memcg-rename-mem_cgroup_ino-to-mem_cgroup_id.patch removed from -mm tree

[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: memcg: rename mem_cgroup_ino() to mem_cgroup_id()
has been removed from the -mm tree.  Its filename was
     memcg-rename-mem_cgroup_ino-to-mem_cgroup_id.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: memcg: rename mem_cgroup_ino() to mem_cgroup_id()
Date: Thu, 25 Dec 2025 15:21:16 -0800

Rename mem_cgroup_ino() to mem_cgroup_id() and mem_cgroup_get_from_ino()
to mem_cgroup_get_from_id().  These functions now use cgroup IDs (from
cgroup_id()) rather than inode numbers, so the names should reflect that.
